Technical Feasibility & Architecture
⚙️ Technical Achievability
LocalPerks leverages mature technologies and well-established patterns. The loyalty program mechanics are straightforward CRUD operations, mobile QR scanning is standard, and payment processing can use existing providers like Stripe. The coalition model adds complexity but doesn't require novel technical solutions. React Native enables cross-platform mobile development, while modern web frameworks handle business dashboards efficiently. Primary risks are operational (business onboarding, consumer adoption) rather than technical barriers.
🛠️ Recommended Technology Stack
📱 Frontend Stack
Web Dashboard: Next.js + TypeScript
UI Framework: NativeBase + Tailwind CSS
State Management: Zustand
React Native with Expo provides rapid cross-platform development with native QR scanning capabilities. Next.js offers excellent developer experience for business dashboards with server-side rendering for SEO. TypeScript prevents runtime errors in financial transactions.
⚡ Backend Stack
Database: PostgreSQL (Supabase)
ORM: Prisma
Auth: Supabase Auth + JWT
Node.js enables code sharing between mobile and backend. PostgreSQL provides ACID compliance crucial for financial transactions. Supabase offers managed database, auth, and real-time subscriptions, reducing infrastructure complexity significantly.
💳 Payments & Services
Email: Resend
SMS: Twilio
Analytics: PostHog
Stripe Connect handles marketplace payments between businesses and settlement. Resend provides reliable transactional emails. PostHog offers product analytics with privacy compliance. All services have generous free tiers for MVP validation.
☁️ Infrastructure
Storage: Supabase Storage
CDN: Vercel Edge
Monitoring: Sentry
Vercel provides zero-config deployment for Next.js with global CDN. Railway offers simple backend deployment with automatic scaling. Combined cost under $100/month until significant scale, then predictable pricing tiers.

💾 Data Requirements & Strategy
📊 Core Data Models
- Users: Consumer accounts, preferences, contact info
- Businesses: Locations, owners, settings, coalition membership
- Transactions: Points earned/redeemed, amounts, timestamps
- Coalitions: Business groups, rules, admin settings
- Points Ledger: Double-entry accounting for all point movements
📈 Storage Estimates
- Year 1: 10K users, 500 businesses → ~2GB
- Year 3: 100K users, 2K businesses → ~50GB
- Transaction volume: ~1M records/year at scale
- Media storage: Business photos, logos → 10-20GB
- Cost: <$100/month storage through Year 3
🔒 Privacy & Compliance
PII Handling: Phone numbers, emails encrypted at rest. GDPR/CCPA: User data export/deletion APIs built into core system. Financial Data: PCI compliance through Stripe, no card data stored locally. Location Data: Business addresses only, no user location tracking.

⚠️ Technology Risks & Mitigations
Stripe Connect Dependency Risk
HIGH SEVERITYEntire business model depends on Stripe's marketplace payments. Rate limit changes, policy updates, or service outages could cripple operations. Settlement complexity requires deep Stripe Connect integration.
Points Ledger Complexity
MEDIUM SEVERITYCross-business point redemptions create complex accounting scenarios. Edge cases around partial redemptions, refunds, and business exits could create ledger inconsistencies.
Mobile App Store Approval
LOW SEVERITYApp store policies around financial apps and loyalty programs could delay launch. Apple/Google may require additional compliance documentation or reject certain features.
Scalability Bottlenecks
MEDIUM SEVERITYDatabase queries for point calculations and business analytics could become slow at scale. Real-time features may struggle with high concurrent usage during peak hours.
